Hi all, anyone who knows what's the special thing with TmapMigratePP.DataScan case. When I introduce thread_local variable in PR(https://github.com/ceph/ceph/pull/9783/files#diff-254a8401d238ec25c714a5596f85b5ebL64), it always failed because the thread local variable is assigned to zero when execute this test! For example, when tid == 512596224 local_center should be 5fed4e48, but after begin this test case, this thread_local variable is assigned to zero!: tid=-512596224 local_center=5fed4e48 this=5fed4e48 [New Thread 0x7fffdef21700 (LWP 11835)] tid=-512596224 local_center=5fed4e48 this=5fed4e48 [New Thread 0x7fffde720700 (LWP 11836)] [New Thread 0x7fffddf1f700 (LWP 11837)] [New Thread 0x7fffdd71e700 (LWP 11838)] [New Thread 0x7fffdcf1d700 (LWP 11839)] [New Thread 0x7fffdc71c700 (LWP 11840)] [New Thread 0x7fffdbf1b700 (LWP 11841)] tid=-134366272 local_center=0 this=5fed4e48 tid=-134366272 local_center=0 this=5fed4e48 tid=-134366272 local_center=0 this=5fed4e48 tid=-512596224 local_center=0 this=5fed4e48 QA job:http://qa-proxy.ceph.com/teuthology/haomai-2016-06-27_03:55:04-rados-wip-haomai-testing---basic-smithi/279412/teuthology.log This can be repeated locally and I want to know what's the difference this case introduced -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
